The service also will not operate to and from the Seahawks' game against the St. Louis Rams.
The Northline Sounder usually serves as a weekday route for commuters between Everett, Mukilteo, Edmonds and Seattle, but the service has been disrupted more or less continuously since Dec. 17. Prior to that, numerous closures occurred in November because of rainfall.
Gus Melonas, spokesman for Burlington Northern Santa Fe railroad, says continuing damage from heavy rains has made the lines used by the Sounder passenger trains unsafe. He says railroad crews are taking out trees with roots exposed to decrease possibility of debris falling on the lines.
He said the railroad will evaluate slope conditions through the weekend to determine whether passenger rail service can resume on Monday.
One train line has been able to provide freight service.
